Slower speeds make for safer streets

25 Feb 2019

Studies show that speeding is a significant contributing factor leading to severe injuries and fatal collisions worldwide. The likelihood of survival in a collision between a vehicle and a pedestrian is approximately 15 per cent when the vehicle is traveling at 50 km/h. However, the likelihood of survival increases to 75 per cent when the vehicle is traveling at 40 km/h or below.

Studies show that higher speeds not only increase the risk of severe injuries and fatal collisions, but also increase the risk of a collision happening in the first place. Higher speeds increase the distance required to stop safely by reducing both the braking time and the driver’s reaction time available to prevent a collision from happening. A stopping distance of approximately 85 metres is required for a vehicle travelling at 60 km/h, 63 metres for a vehicle travelling at 50 km/h, and 45 metres for a vehicle travelling at 40 km/h.
